A Welsh film that has been painstakingly restored to its former glory is due to be screened today – in a Blaenau Ffestiniog slate mine.
Y Chwarelwr – which translates as The Quarryman - is credited as the first ever Welsh Language 'talking movie’ and is considered an important event in the development of Welsh film.
The original print was damaged and incomplete, but in 2006 Ifor Ap Glyn - of Cwmni Da and the National Screen and Sound Archive of Wales - recovered and restored it to its original condition.
An ending to the film was also created for the lost reels that could not be found.
The screening will be held at the Llechwedd Slate Caverns in Blaenau Ffestiniog, which celebrate their 40th anniversary this year.
